In our previous work, we proposed a vertical organic transistor,space-charge-limited transistor (SCLT) with a high output current (50 mA/cm2) and a high on/off current ratio (＞10000) at low operation voltage (2V) [1].The output current was high enough to drive an OLED.In this report, we demonstrated our recent progress on integrating SCLT with solution-processed OLED.Firstly, we developed process to improve the voltage endurance and the bias stress reliability of SCLT.
